I can't say I remember exactly either, but, for me, Abercrombie really shines with his characters - their development and interactions, so wouldn't surprise me if the first book is a lot of building up that.
The world and story are more generic (not a criticism in any way, just the way it is with a lot fantasy), compared to someone like Sanderson, who's a beast at world-building. If you have time to kill, he's even done a
lecture on it.
